Abstract
pH dependent K/S values, Hue, Value, and Chroma change of the hot-water and alkali extract of Boehmeria tricuspis have investigated as a part of the studies on natural dye resources. Maximum optical absorption of the dyed cotton, Korean paper, and silk with the extract were observed at 400 nm. According to the result of pH dependent K/S values change, it tended to increase as pH decreased except for the silk and there was no change near pH 7. For Hue, the materials dyed with hot-water and alkali extract indicated YR and R color, respectively. The change in Value of the dyed materials tended to increase, whereas Chroma of them decreased as the pH moved to alkali conditions although there were no significant changes near pH 7. As a result, it is considered that the optimum pH would be 7 when the mentioned materials are dyed with Boehmeria tricuspis extract.
미이용 천연염료자원에 대한 탐색연구의 일환으로 거북꼬리(Boehmeria tricuspis Makino)를 선발하고 열수 및 알칼리 조건에서 추출한 추출물을 사용하여 pH 조건에 따른 염착량 및 색상, 명도, 채도의 변화에 대하여 조사하였다. 면, 한지, 실크에 대한 열수 및 알칼리추출물 처리 염색물의 최대흡수파장 (
